Speedster Portia Woodman broke a tense final deadlock and Australia's resistance as the New Zealand women won the latest sevens tournament in Brazil.
A swerve around her marker and a 70m sprint to the line nailed the title and helped confirm Woodman as player of the tournament with her record 13-try haul.
The 17-10 victory, completed with Tyla Nathan-Wong's sideline conversion, topped a difficult programme for New Zealand through the playoffs.
"Portia had a special tournament and played with special confidence after coming back at Dubai from a long-term injury. She did very well but it was only because of the good ball produced inside her," coach Sean Horan said.
